THEFT-WARNING SIGNAL FOB VEHICLES.

Application filed February 7, 1922. Serial No. 534,797..

T 0 all whom it may concern:

Be it known that we, VVILLIAM E. CHAD- WICK and JOHN A. CREIerrroN, citizens of the United States, residing at Los Angeles,

6 in the county of Los Angeles and State of California, have invented a newand useful Improvement in Theft-Warning Signals for- "2'9 which there are no convenient openings through which a positive'connection c'an'be made between the. parts of such aysi'gnal around the rim or tire of the vehicle wheel. Our invention, while especially adapted to '23 be locked around the disc type of wheel, may also be locked to the ordinary type of spoke wheel. 1 i

The invention consists in the novel and useful construction, arrangement and combination of parts, all as herein described, as shown in the drawings herewith, and as hereinafter pointed out in the claims.

In the accompanying drawing- Figure 1 is a front elevation of the device, parts being broken away and in section;

Fig. 2 is a side elevation of a portion of the improved device shown applied to a part of a wheel tire and disk wheel; and i Figure 3 is a-detail of a portion of the device. 7

Corresponding parts throughout the drawing are designated by the same reference numerals.

In the embodiment of the invention shown in the accompanying drawing, A is a rigid curved arin hingedly joined to another rigid curved arm, B, the two arms, A and B, being adapted to partially encircle the tire, v0, and rim, 0, and to bear against the disc portion, 0", of the whee-1,0. A looking' means, D, :is provided for holding the arms the position desired.

The arm, A, is a rigid hook shap'ed member, preferably of steel, adapted to partially encircle the tire, 0, and rim, 0', with a curved portion, t, preferably having its concave surface touching the tire,"c, as at 5, and'one end, 6, adapted to bear against the disc, 0'', of the wheel, G. A pa'd,r7, of yielding material may be attached to the end, 6,- as at 8, to prevent the marrin-g of the enamel or platw ing on the disc. A projecting point, 9, is formed on the arm, A, so as to protrude substantially as in Figure 2, from the periphery of the tire, 0, when the device is'in place on the wheel, C. The point, 9-, is for the purpose of striking the pavement and lifting the vehicle as the wheel rotates, thus producing a noise and attracting the attention of passersby, at the same 'timerl'eaving an easily followed trail, due to the action of the point 9 on the roadway, should 'a' theft be effected in spite of the noise produced.

The opposite end'of the arm, A, is shaped as best shown in Figure 3, having a rounded and flattened portion, 10, "slotted on its ipe riphery, as at 10 and drilled, 'as'at 11', for a hinged pin, 11, providing for a hinged connection with arm, B. Hinge pin, 11, is also received in hole, 11 drilled in thebi; furc-ated end, 13, of arm, B, and may be welded or fixed therein in assembly with arm A. Portion, 10, of arm, A, is received in the slot 12* of the end 1 3. Adjacent the end, 13, of arm, B,"is a cavity, as at 12, L

formed in the body of the arm, and in which locking means, D, is inserted. The opposite end, 14:, of arm B is formed as at 15, and to it a ":pad,16, similar to pad, 7 and for a like purpose, may be attached. When the signal is attached to a wheel, pads 7 an-d16 come oppositecach other and with sufiicient aperture between them' to accommodate the disc, v), and are locked in that position by the locking means, D, hereinafter-described.

' Locking means D consists of a lock barrel, 17 of well known construct-ion, held in place in the cavity at "12 by a pin or screw 18, let into. the arm B from the inner -'surface of the slot 12*. Said pin or screw, 18, may be welded or brazed 'over, 'so'as not to be readily accessible for tampering with the locking means D. Attached ,to the shaft,

and 16 are in contact With the Wheel disc, 0", the slot at 10 is in alignment With the portion 12 of cavity 12*. Hence, When the arms are in the aforesaid position, locking bar, 21, may be rotated through theslot at 10 by means of the key 22, and the mechanism of the lock barrel 17 may be so arranged that When the bar 21 is in the position shown in the drawing, the key, 22, may be Withdrawn and the mechanism of the lock barrel, 17 Will hold the bar in that position. The face 21 of the bar21, Will bear against the sides of the slot at 10 and prevent any relative movement of the arms A and B. The signal device is thus locked against removal from s the Wheel. The ends-6 and 1 1 bearing against the disc, 0 prevent the rotation of the signal around the tire c and rim 0. When in place on other types'ofvehicle Wheels, the ovular formof the opening between the arms and the substantially ovular form of the tire and rim Will prevent rotation of the device about the tire and rim.

It is obvious that many changes and modifications may be'made in practicing my invention Without departing from the true spirit'and scope thereof.

Having thus disclosed our invention, We claim and desire to secure by Letters Patent 1. A device of the class specified, comprising tire embracing arms differing in length and having'ends pivotally connected to form a hinge, the longer arm having a lower projecting point, and locking means located adjacent to the hinge and consisting of a fixed terminal fiat disk carried by the longer arm and having a transverse slot through the periphery thereof, the shorter arm having a slot in its end to receive said disk and also having therein an eccentrically mounted oscillatable locking device, said v locking device being disposed at right angles to the fiat disk and movable through the peripheral slot of the latter. i

2. A device of the class specified, comprising tire embracing arms differing in length and having ends movably associated to form a hinge connection, the longer arm having a projecting point, and locking means carried by the arms at the hinge connection and respectively including a rigid disk With a peripheral slot located at the terminal of the longer arm, the slot of the disk being above the means for connecting the arm ends, and the shorter arm provided with, an oscillatable eccentricallymounted locking member located above and operable at right angles to and movable through the peripheral slot of the disk.

3. A device of the class specified comprising tire-embracing arms having ends respectively formed With a slot and a fiat rigid disk member to movably engage'the slot, and

said disk.

naeasss an oscillatable member movable in the arm having the slot and in a plane at right angles to the disk at the end of the other member and also through the slot of the 4-.
